Copper metal reacts with hot concentrated sulfuric acid solution to form aqueous copper (II) sulfate, sulfur dioxide gas, and water. Write the balanced chemical formula.
Find out the required pressure to compress 180 liters of N at 1.0 atm into a tank whose volume is 34 liters.
If we took EXACTLY 1.00 ml of a 1.000 M solution of Cu(NO3)2 and placed it in 99.000 ml of water and mixed it, then took 2.00 ml of this solution and placed it in 18.000 ml of water.
